问题描述

您好，我是Android开发领域的新手我正在尝试制作一个可在收到特定短信时更改铃声配置的应用程序，也可以通过布局上的按钮(按钮运行良好)来更改铃声配置，但短信方式不起作用

Hello there i'm newbie in Android development I'm trying to make an app that changes the ringer profile when receive a specific sms, also i can change it by the buttons on the layout (the buttons are working good), but the sms way isn't working

我尝试如下所示

MainActivity.java

package com.example.test;
import android.media.AudioManager;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;


public class MainActivity extends Activity {

   private Button Vibrate , Ring , Silent , Mode;
   private TextView Status,sms;
   public static AudioManager myAudioManager;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);


      Vibrate = (Button)findViewById(R.id.button2);
      Ring = (Button)findViewById(R.id.button4);
      Silent = (Button)findViewById(R.id.button3);
      Mode = (Button)findViewById(R.id.button1);
      Status = (TextView)findViewById(R.id.textView2);
      sms = (TextView)findViewById(R.id.sms);

      myAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

   }

   public void vibrate(View view){
       myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
   }
   public void ring(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
   }
   public void silent(View view){
      myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
   }
   public void mode(View view){
     int mod = myAudioManager.getRingerMode();
     if(mod == AudioManager.RINGER_MODE_NORMAL){
         Status.setText("Current Status: Ring");
   }
   else if(mod == AudioManager.RINGER_MODE_SILENT){
       Status.setText("Current Status: Silent");
   }
   else if(mod == AudioManager.RINGER_MODE_VIBRATE){
      Status.setText("Current Status: Vibrate");
   }
   else{

   }
  }
   public static void messageProcessing(String message) {
       if(message=="ring") 
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
       else if (message=="vibrate")
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
       else if(message=="silent")
           myAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

   }
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.main, menu);
      return true;
   }

}

ReceiveveSMS.java

package com.example.test;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.widget.Toast;
import android.os.Bundle;

public class RecieveSMS extends BroadcastReceiver 
{   
    public static final String SMS_BUNDLE = "pdus";

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle intentExtras = intent.getExtras();
            if (intentExtras != null) {
                Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
                for (int i = 0; i < sms.length; ++i) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                    String smsBody = smsMessage.getMessageBody().toString();

                    MainActivity.messageProcessing(smsBody);

                    Toast.makeText(context, smsBody, Toast.LENGTH_SHORT).show();
                }
            }
    }
}

有什么帮助吗?另外，这个应用程序是否在后台运行，还是我应该提供服务以实现这一目标?

any help ?? also , well this app work in background or i should make a service to make that happen ?

推荐答案

我找到了一种解决问题的方法，就是这样:

I found out a way to solve my problem and that's how :

package com.example.test;

import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.SmsMessage;
import android.widget.Toast;
import android.media.AudioManager;
import android.os.Bundle;

public class RecieveSMS extends BroadcastReceiver 
{   
    public static final String SMS_BUNDLE = "pdus";

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle intentExtras = intent.getExtras();
            if (intentExtras != null) {
                Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
                for (int i = 0; i < sms.length; ++i) {
                    SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                    String smsBody = smsMessage.getMessageBody().toString();
                    //Edited from here
                    if (smsBody.contains("silent"))
                    {
                    Intent in = new Intent(context, MainActivity.class);
                    PendingIntent pendingIntent = PendingIntent.getActivity(context,
                    12345, in, PendingIntent.FLAG_CANCEL_CURRENT);
                    AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
                    am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                    //To here
                    }

                    Toast.makeText(context, smsBody, Toast.LENGTH_SHORT).show();
                }
            }
    }
}
